Nomenclatural History

Mytilococcus
Amerling
1858a: 101.
Type species: Mytilococcus communis Amerling
by monotypy and original designation
.
(= Lepidosaphes ulmi, Linnaeus )
nomen nudum
(Balach1954e: 28-30)
Notes: Lindinger (1936) insisted that the generic name Mytilococcus Amerling, 1858, had precedence over Lepidosaphes Shimer, 1868. Morrison & Morrison (1966) questioned this substitution because the name was never spelled consistently (Amerling lists it as Mytillicoccus, Mytilococcus and as Mytilicoccus), there was no generic description to associate with the name and no specific descriptions associated with any of the forms named in association with Mytilococcus. Most current coccid workers (Balachowsky, Borchsenius, Ferris, Hall, Schmutterer, Takahashi) have used Lepidosaphes as the senior name.

Mytilaspis
Targioni Tozzetti
1868: 737.
Type species: Mytilaspis linearis Targioni Tozzetti
by subsequent designation
Lindin1936:149
.
junior synonym
(Fernal1903b: 304)
Notes: Signoret suggested that the name Mytilaspis Targioni Tozzetti was older than Lepidosaphes Shimer, which was published in January 1868. Morrison & Morrison (1966) found no evidence to support this allegation and they concluded that Lepidosaphes has priority over Mytilaspis. Over the years, many coccid workers have incorrectly listed Signoret as the author of Mytilaspis.

Scobinaspis
MacGillivray
1921: 274.
Type species: Mytilaspis serrifrons Leonardi
by monotypy and original designation
.
junior synonym
Notes: Ferris (1937) made Scobinaspis dentata the type species of Velataspis and stated that it was not particularly related to S. serrifrons, but Balachowsky (1954e) moved S. serrifrons to Velataspis also. This action would make Scobinaspis the senior synonym of Velataspis, but this synonymy was not supported by other authors. Danzig (1993) however, considers Scobinaspis as a junior synonym of Lepidosaphes and does not treat Velataspis.

Parainsulaspis
Borchsenius
1963: 1162-1163.
Type species: Lepidosaphes laterochitinosa Green
by original designation
.
replacement name that is a synonym
(Takagi1970: 1)
Notes: Borchsenius (1963) states that Parainsulaspis is a replacement name for Cephalaspis MacGillivray 1921 which is preoccupied by Cephalaspis Agassiz 1835 in Pisces. However, Borchsenius changed the type species from MacGillivray's choice of Mytilaspis cocculi Green 1896 to Lepidosaphes laterochitinosa Green 1925, which is not in accordance to Article 67.8 of the ICZN. See Russell (1970) for further information.

Remarks

Systematics: Borchsenius (1962b and 1963) divided Lepidosaphes into 10 smaller genera. We here agree with Takagi (1970) and Danzig & Pellizari (1998) that the genus should remain in tact and the smaller genera are here considered junior synonyms.

Structure: Female body fusiform, usually with well developed lateral abdominal lobes, these with marginal gland spines, or gland tubercles further forward. Median lobes (L1) not yoked, separated, with 1 pair of gland spines in medial space, L2 bilobed, paraphyses if present short, L3 insignificant.
The three burrowing species of Lepidosaphes differ from the non-burrowing species of the genus in having dentate or serrate trullae. Macroducts exhibit a tendency towards reduction in number, size, or shape. (Takagi, 2003)
Dorsal ducts 2-barred, usually 6 pairs of marginal macroducts, ducts on submargin and submedian abdomen often numerous, with similar ducts also on submargins of anterior abdomen and thorax. Dorsal submarginal bosses often present. Lateral tubercles or spurs often present between some abdominal segments. Perivulvar pores present in 5 groups. (Henderson, 2011)
